The Geometry of Ultra-Fast Outflows Probed by Soft X-ray Variability in PDS 456
Riki Sato, Kouichi Hagino, Toshiya Iwata +20
Constraining the location and geometry of ultra-fast outflows (UFOs) is essential for identifying where they are launched and how they are accelerated. We investigate the soft X-ra…
Time-evolving Diagnostic of the Ionized Absorbers in NGC 4051. II. High-throughput Time-resolved Spectroscopy
Alfredo Luminari, Fabrizio Nicastro, Roberto Serafinelli +5
Active Galactic Nuclei (AGNs) are one of the most powerful sources in the Universe. The accretion-liberated energy can strongly impact the surrounding environment, up to the host g…
Fe K line from the Broad Line Region of PDS456 with XRISM/Resolve
Alfredo Luminari, Fabrizio Nicastro, Stefano Bianchi +1
The high-luminosity, high-mass and likely super-Eddington quasar PDS 456 is known for its extremely dynamic environment. A wealth of observational features from the millimetric up…
The WISSHFUL program: the highest redshift UFO discovered in a non-lensed QSO
G. Lanzuisi, L. Borrelli, E. Piconcelli +28
We present the first results from the WISSHFUL program, an XMM-Newton heritage program targeting luminous QSOs at Cosmic Noon. We report on recent simultaneous XMM-Newton and NuSTA…
Is XRISM/Resolve probing a "raining" absorber in Mrk 509?
M. Dadina, V. Missaglia, V. Braito +19
X-ray spectroscopy of AGN offers unique insights into the reprocessing of radiationand gas dynamics near SMBH. The Sey 1 galaxy Mrk 509 is an ideal laboratory for these studies sin…
Unveiling the dynamics of the ultra-fast outflow in IRAS 13224-3809 with X-ray spectroscopy
Pierpaolo Condò, Francesco Tombesi, Marco Laurenti +9
IRAS 13224-3809 is one of the most intensively studied narrow-line Seyfert 1 galaxies, with a rich literature reporting diverse and sometimes contrasting interpretations of its com…
